LIFEMENT Basic 6 Inch Full Cooling Gel Memory Foam Mattress in a Box, Medium Firm | Gel Infused, Fiberglass Free, CertiPUR-US & OEKO-TEX Certified

The LIFEMENT Basic Cooling Gel Memory Foam Mattress — Smarter Sleep, Night After Night Getting quality sleep should not require spending a fortune. The LIFEMENT Basic Cooling Gel Memory Foam Mattress delivers the pressure-relieving comfort of premium memory foam with the safety features and certified materials that every home deserves — all at an accessible price point that does not compromise where it matters most. Cooling Gel Technology That Works All Night Traditional memory foam is notorious for trapping body heat, creating an uncomfortably warm sleep surface that disrupts rest throughout the night. The LIFEMENT Basic Cooling Gel solves this with gel beads infused throughout the top comfort layer. These gel beads actively absorb excess body heat as you sleep and dissipate it away from the sleep surface, preventing the heat retention common in standard memory foam. Combined with an open-cell foam structure that promotes continuous airflow within the foam itself, the result is a consistently cool, dry, and comfortable sleeping environment from the very first night. Three-Layer Construction Engineered for Support Every inch of the LIFEMENT Basic Cooling Gel mattress is engineered with a purpose: Top layer (cooling gel memory foam) — Gel-infused open-cell memory foam contours precisely to the curves of your body, relieving pressure points at the shoulders, hips, and lower back. The open-cell structure enhances airflow within the foam while the gel beads draw heat away from the sleep surface throughout the night. Middle transition layer — Bridges the gap between the soft comfort layer and the firmer base, absorbing motion and preventing it from transferring across the mattress. Partners, pets, and restless sleepers will not disturb each other. Base support layer (high-density foam) — Provides the foundational stability that keeps the mattress from sagging over time. The higher foam density ensures this mattress holds its shape and support for years of use. Medium-Firm Feel for All Sleep Positions At a medium-firm comfort level (6 out of 10 on the firmness scale), the LIFEMENT Basic Cooling Gel strikes the balance that accommodates the widest range of sleepers. Back sleepers get the spinal alignment support they need. Side sleepers get enough give to relieve hip and shoulder pressure. Stomach sleepers get the firmer surface that keeps the midsection from sinking. Whether you sleep alone or share a bed, this mattress adapts without compromise. Fiberglass-Free and Certified Safe Some mattresses use fiberglass as a fire barrier hidden inside the cover — a practice that can result in harmful fiber contamination if the cover is ever removed or damaged. The LIFEMENT Basic Cooling Gel uses no fiberglass anywhere in its construction. All materials meet the stringent standards of two independent certification programs: CertiPUR-US, which verifies that the foam is made without ozone depleters, formaldehyde, heavy metals, or harmful flame retardants, and OEKO-TEX Standard 100, which certifies that every component of the finished product has been tested for harmful substances. You can sleep with complete confidence. Mattress-in-a-Box Convenience The LIFEMENT Basic Cooling Gel ships compressed and vacuum-sealed in a compact box designed to navigate staircases, narrow hallways, and apartment doorways with ease. Setup could not be simpler: remove the box, position the mattress on your base, cut away the packaging film, and allow 24 to 72 hours for the mattress to fully expand and off-gas before sleeping on it. No assembly tools, no white-glove delivery coordination, and no awkward maneuvering of a full-size mattress. Compatible With Most Bed Frames and Bases The LIFEMENT Basic Cooling Gel works with virtually any foundation: platform beds, box springs, slatted bases (slats no more than 3 inches apart), and adjustable bases. It does not require a box spring to perform correctly, making it ideal for platform frames and floor placement. Suited for master bedrooms, guest rooms, bunk beds, daybeds, trundle beds, college dorms, and first-apartment setups.
